Comparing and Ordering 3-Digit Numbers

Use place value to compare, order, and explain numbers

Math - Grade 2-3

Instructions: Read each problem carefully. Use place value to compare the numbers. Show your work in the space provided.
  1. 1

    Compare the numbers. Write <, >, or = in the blank: 426 ___ 462.

    Start by comparing the hundreds place, then the tens place.

    426 is less than 462, so the correct symbol is <. The hundreds are the same, but 2 tens is less than 6 tens.
  2. 2

    Which number is greater: 718 or 781? Explain how you know.

    781 is greater than 718. Both numbers have 7 hundreds, but 781 has 8 tens and 718 has 1 ten.
  3. 3

    Order these numbers from least to greatest: 305, 350, 315.

    All three numbers begin with 3 hundreds, so compare the tens place next.

    The numbers in order from least to greatest are 305, 315, 350. They all have 3 hundreds, so the tens and ones places help decide the order.
  4. 4

    Order these numbers from greatest to least: 684, 648, 846.

    The numbers in order from greatest to least are 846, 684, 648. 846 has the most hundreds, and 684 is greater than 648 because 8 tens is greater than 4 tens.
  5. 5

    Look at the base-ten blocks. Number A has 5 hundreds, 3 tens, and 8 ones. Number B has 5 hundreds, 6 tens, and 1 one. Which number is greater?

    Build each number from the hundreds, tens, and ones.

    Number B is greater. Number A is 538 and Number B is 561, and 561 is greater because it has more tens.
  6. 6

    Compare the numbers. Write <, >, or = in the blank: 909 ___ 990.

    909 is less than 990, so the correct symbol is <. The hundreds are the same, but 0 tens is less than 9 tens.
  7. 7

    Circle the smallest number: 472, 427, 724, 247.

    The number with the fewest hundreds is the smallest.

    247 is the smallest number. It has 2 hundreds, while the other numbers have 4 hundreds or 7 hundreds.
  8. 8

    Fill in the blanks to order the numbers from least to greatest: 619, 691, 601, 610. ____ , ____ , ____ , ____

    The numbers in order from least to greatest are 601, 610, 619, 691. They all have 6 hundreds, so compare the tens place and then the ones place.
  9. 9

    A class collected 236 cans on Monday, 263 cans on Tuesday, and 326 cans on Wednesday. Which day had the greatest number of cans collected?

    Compare the hundreds place first.

    Wednesday had the greatest number of cans collected. 326 is greater than 236 and 263 because it has 3 hundreds.
  10. 10

    Use the number line to answer. Which number is closer to 500: 489 or 521?

    Count how far each number is from 500.

    489 is closer to 500. It is 11 away from 500, while 521 is 21 away from 500.
  11. 11

    Compare the numbers. Write <, >, or = in the blank: 777 ___ 777.

    777 is equal to 777, so the correct symbol is =. Both numbers have the same hundreds, tens, and ones.
  12. 12

    Order these numbers from greatest to least: 120, 210, 201, 102.

    Group the numbers by hundreds first.

    The numbers in order from greatest to least are 210, 201, 120, 102. The numbers with 2 hundreds come before the numbers with 1 hundred.
  13. 13

    Look at the place value chart. Number A is shown as 4 hundreds, 8 tens, and 0 ones. Number B is shown as 4 hundreds, 0 tens, and 8 ones. Compare Number A and Number B.

    Number A is greater than Number B. Number A is 480 and Number B is 408, and 8 tens is greater than 0 tens.
  14. 14

    Mia wrote the numbers 563, 536, and 653. Put the numbers in order from least to greatest.

    Compare 536 and 563 carefully before comparing them to 653.

    The numbers in order from least to greatest are 536, 563, 653. 536 and 563 have 5 hundreds, and 536 has fewer tens than 563.
  15. 15

    A number has 8 hundreds, 2 tens, and 9 ones. Another number has 8 hundreds, 9 tens, and 2 ones. Which number is less?

    Write each number first, then compare the tens place.

    829 is less than 892. Both numbers have 8 hundreds, but 829 has only 2 tens and 892 has 9 tens.
